The color, spread with brushes and spatulas, gives the picture a solid architectural structure that takes place on the double register of lights and shadows. The coloristic substance, reduced to the minimum terms, possesses an allusive and suggestive power that relies on the Manichaean relationship between full and empty, between order and chaos. The rhythms of black and white counterpoints express a lyrical feeling that some exegetes of the artist have compared to asceticism.
